Baby's Movement

Hi mga mamsh. I am really worried as I am not feeling yet any minimal movement by my little one inside. I am 20wks 3 days today. I've been reading some that as early as 18 weeks may nafi feel na sila. As to my case wala tlaga and Im starting to feel paranoid. I tried using doppler and naririnig ko naman may heartbeat. Any first time moms too na naka experience din ng late na tlaga na may nafeel? Nxt week pa kasi pre natal ko. Thankyou! ❤
